The SPC is considering extending the Tornado Watch for south Mississippi:

SUMMARY…Threat for damaging winds and perhaps a couple of tornadoes will potentially focus over southeastern Louisiana and parts of southern Mississippi later tonight. A replacement watch may be considered prior to the 07Z expiration of Watches 111/113.

DISCUSSION…An expansive mesoscale convective system continues late this evening across the lower Mississippi Valley. While a considerable precipitation shield over northern Louisiana and central/northern Mississippi has limited the northward progress of a warm front, deep/moist southerly flow across the warm sector is maintaining robust convective elements within the broader system.

There has been a relative lull in severe reports recently, but a modest uptick in the potential for damaging winds (and perhaps a couple line-embedded tornadoes) may occur. With increasing large-scale ascent associated with an approaching impulse, cells should organize into a more focused meridional line from southeastern Louisiana northward into Mississippi. MLCAPE values around 1500-2500 J/kg will likely support a squall line that advances towards the central Gulf Coast through the overnight. Line-parallel low-level shear vectors suggest primarily an occasional damaging-wind threat with this line. However, the amplitude of low-level shear may also favor small-scale embedded circulations. A replacement watch could be considered prior to the 07Z expiration of Watches.

Nick is a weather nerd to the core. He graduated from Oregon State University n 2008 with a Bachelor of Science in Earth Science with an emphasis in Atmospheric and Oceanic Sciences. In 2010, he decided that he wanted to pair his love of journalism with his passion for weather. So, he enrolled at Syracuse University to earn his Masters of Science in Broadcast & Digital Journalism.After forecasting for media outlets in Syracuse, New York and Amarillo, Texas he is now in Hattiesburg, Mississippi where he works as the Chief Meteorologist for a local television station and works part time as an Adjunct Professor teaching a course in meteorology.
